JOHN annnnrbnoeunrrn, or orrAwA, onrranro, camera FLUID TURBINE.

Application filed November 7,1924. Serial No. 38,404.

This invention relates to improvements in a fluid turbine and hasfor 'a particular ob ject to provide a devlce of that classhaving' a rotor acted on by a tangentially directed force feed the velocity of which 1S increased by the diminution of the raceway dimensions.

A further object is to provide such a tur- I ence indicate like parts throughout the sev eral views,

Fig. 1 is 'a longitudinal vertical section of an embodiment of this invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is atransverse vertical section taken onthe line 34-3 of Fig.1;

Fig. 4 is an end elevation and I, Fig. 5 is a perspective of the means em ployed for mountingand moving the velocity increasing elements.

This improved turbine is housed within 1 a cylindrical casing 6 having ends 7 removably applied thereto by the bolts 8. A

nalled. in the ends 7 has longitudinal ribs or vanes 11 extending angularly therefrom. 'A diagonal pair of fluid inlet ports 12 and 13 respectively are threaded to receive the supply pipes (not shown). Theoutlet discharge ports 14 and 15 are adjacent though spaced from said inlets and intermediate the adjacentpairs of said ports are inwardly directed extensions 16 and 17 that have frictioned clearance with the vanes 11. As will be noted on reference tothe drawings, these extensions with a straight face adjacent the discharge port provide interruption for the spent fluid directing it through the said outlet while the incline of the remote side form g? masseuse .qf the inlet or feed forming a part. of this port projects the fluid on the tangent of the rotor 9. It will thus be apparent that two raceways 18 and 19 are provided in which two independent, individual and distinct forces are applied to the rotor 9 without in any wayinterfering with or hindering the operation and eifectivenessof the other.

The rate of revolution of the wheel 9 which is dependent on the velocity and pressure of the motive imparting fluid such as water or a liquid fed through theinlet ports 12 and 13 is increased by the provision of raceway dimension diininishers' 20 one of which is mounted in each raceway and preiferably diagonally opposite eachother.

Thesevelocity'increasing elements 20 are inward extensions from the casing 6 disposed transversely of the lines of pressure in the raceways and may be formed integral with said'casing. The present embodiment however illustrates these current deflectors 9.0

as being carried by discs 21 and 22 that are interposed between the ends of the casing and therotor 9; This is to provide for adjustment of their position and the hub of disc 21 projectingthrough the end of the casing 7 as at 23 provides a bearing for the shaft 10 thereat and terminates in a. gear I 2a with which a manually operable worm 25 co-operates.

' The deflectors above described may be provided with an inclined face on the pressure side and if adjustable will cont-act closely with the inner wall of the casing; thus by reducing thepassage an increased velocity is provided without creating any material back pressure. So it will be seen that by the actuating of the manually operated worm,

25, these diametrically opposite deflectors 20 may be adjusted circumferentiallyto in crease or diminish the head of the driving propellant or to act as closures for either the inlet oroutlet ports.

From the foregoing description taken in connection with the accompanying drawings,

it will be manifest that a fluid turbine is provided which will fulfill all the necessary requirements of such a device but as many changes could be made in the above description and many apparently widely'diiierent embodiments of my invention. constructed within the scope of the appended claims without departing from th spirit or sc pe shaped members.

3. 'In a turbine of the character described,

thereof, it is intended that all matters contained in the said accompanying specification and drawings shall be interpreted as illustrative and not in a limited sense.

hat I claim as new and desire to secure by Letters Patent is:

1. In a turbine of the character described, the combination of a cylindrical casing having a. pair of diametrically opposed fluid discharge ports, a pair of diametrically op posed fluid inlet ports preyided closely adjacent said discharge ports, inwardly extending projections between each adjacent )air' ol inlet and discharge ports; and a rotor housed within said casing, said inwardly extending" projections being in sub stantially fluid tight contact with or proximity to said rotor, and circumferentially adjustable means for restricting the space between the vanes of the rotor and the casing at a point between said projections.

2. In a turbine of the character described, the combination ot a cylindrical casino having pair of dian ietrically opposed fluid discharge ports, a pair of diametrically opposed fluid inlet ports provided closely adjacent said' fluid discharge ports, and inwardly extending projections between each adjacent pairof inlet and discharge ports, to direct fluid tangentially onto the vanes of therotor i and from the vanes into the discharge ports; a rotor housed within saidcasing', said in wardly extending projections being in substantially fluid tight contact with or proximity to'said rotor, diametrically opposed wedge-shaped members in fluid tight contact with the casing and parallel to the axis of the rotor, disks for rigidly connecting said members, interposed between the ends of the rotor of the casing, and means for rotating said 'disks irom' the exterior of the easing to adjust the position of said wedge 1,ee1,71e

the combination of a c lindrical casin having a pair of diametrically opposed fluid dis charge ports, a pair of diametrically opposed fluid inlet ports provided closely adjacent said discharge ports and inwardly extending projections between each adjacent pair of inlet and discharge ports, and shaped on one side to direct fluid from the inlet ports tangentially onto the vanes ot' the rotor and on the other side to direct the fluid from the vanes into the discharge ports; a rotor housed within said casing, said in wardly extending project-ions being in substantially fluid tightcontact with or proximity to said rotor; and circuinterentially adjustable means for restricting the space between the vanes of the rotor and the casing at a point between said projections.

at. In a turbine of the character described, the combination of a cylindrical casing having a pair or diametrically opposed fluid discharge ports, a pair of diametrically opposed fluid inlet ports provided closely adjaeent'said fluid discharge ports, and inwardly extending project-ions between each adjacent pair of inlet and discharge ports and shaped on one side to direct fluid from the inlet ports tangentially onto the vanes 01" the rot-or fluid tight contact with or proximity to said rotor; diametrically opposed wedge shaped members in fluid tight contact with the c'asing and parallel to the axis of the rotor; disks for rigidly connecting said members, interposed between the endsot the rotor and the casing and means for rotating said disks from the exterior of the casing.

In testimony whereof I hereunto aflix my signature.
